Speed of driver = 5 miles/hours
Distance to be covered = 62.8 miles
<u />
<u>F O R M U L A ~ U S E D</u>
Speed = Distance/Time
<u>S O L U T I O N </u>
Time = Distance/Speed
= 62.8 miles / 5 miles / hour
= 12.56 hours
It will take 12.56 hours to cover 62.8 miles, if the driver is moving
with 5 miles/hours
Angle sum property:
55+angle+90= 180
angle=180-145
=35
If the use of calculator is permitted then calculate 1/cos 35 (or sec 35) and you will get 1.22 approximately.
Reason for doing this was that x(hypotenuse)/10(perpendicular) = sec theta .
therefore now you get:-
x/10=1.22
multiply both sides by 10 and get
x= 12.2
Answer is Option A.
9 Floor
32 Rooms
To find total multiply 9 and 32 to get 288 total rooms.
1/3 of the bottle was filled in 1/6 of a minute.
We want to achieve
3/3=1
of the bottle filled, as this will mean the bottle is full.
Since
3/3=3×1/3
, we can find the total time as:
3×1/6=3/6=1/2.
So it will take
1/2 of a minute to fill the bottle.
